Sena SMH3 Bluetooth Headset & Intercom

The SMH3 is a Bluetooth 3.0 stereo headset with Bluetooth intercom designed specifically for motorcycles and scooters. With the SMH3, you can call hands-free on your Bluetooth mobile phone, listen to stereo music, and have two-way intercom conversations in full duplex with a passenger or other riders.

Thanks to the Bluetooth 3.0 and the advanced digital signal processing technology, the SMH3 offers the best sound quality for both incoming and outgoing sound in its class. Also, the easy-to-access and intuitive two-button operations make the SMH3 a perfect companion for motorcycles.

Unibody Design & Two-button User Control

The SMH3 has a unibody design that integrates the main unit, control panel, speakers and microphone, ensuring simple installation. Intuitive two-button user interface is provided on the boom microphone within a quick hand’s reach.


One of the main important factors of using a headset is to stay connected and having Bluetooth capability is a must when on the road. All of Sena’s headsets come standard with Bluetooth 3.0 technology which allows riders to wirelessly make mobile calls, listen to stereo or MP3 player music or audio instruction of GPS navigation. Riders can also effortlessly hold conversations with another motorcyclist or the passenger via the Bluetooth intercom system.

Audio Sound

An important feature customers value is the quality of the audio sound from their headset. Sena’s full product line provides crystal clear, natural sound quality, and is integrated with an audio booster providing sufficient sound level for noisy environments. With a noise reduction mechanism built into the headset rides can enjoy a clear and loud level of audio with audio boosting.

Voice Prompt

Voice prompt is a recorded voice message that is played from the device operations. Sena has integrated voice prompts into all of their units to allow riders to understand the device status instantly with voice feedback. Sena provide voice prompt options for multi-language, English, French, German, Italian, and Spanish.
